The dream of nuclear fusion triggers investment in experimental reactors. New technologies, such as high-temperature superconductors, bring the possibility of achieving it closer.
Harnessing thermonuclear fusion and introducing it into the world's power grids could help make all our carbon dioxide-spewing coal- and gas-fired power plants a distant memory. Nuclear fusion power plants could deliver carbon-free electricity that flows day and night, without worrying about wind or weather; and without the drawbacks of today's nuclear fission plants.
